1'0 all whom it may-concern.-

Be it known that I, JAMES L. BUGBEE, of the city and county of Providence, and State of Rhode Island, havcinvented a newand useful Improvement in Spool-WVinding Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,'forming a part of this specification.

My invention relates to machines for winding cotton thread onto rotating spools in layers of gradually-increasing lengths as the spools are filled or built up with thread against the angular flanges or ends.

In spoolingmachines it is desirable to have a machine adapted to readily and efficiently wind spools of irregular forms as well asspools of regular or standard forms. The standardform spool has the conical flanges or inner faces of the two ends of the same spool of the same angnlarity relative to the spool-body, whereas the irregular or defective form of spool has the flanges of thetwo ends of the same spool each of a different angularity relative to the spool-body. To wind aset ofspools of standard form it is required to have the traverse rod carrying the several threadguid-es make an increasing uniform traversethat is, to travel equal distances relative to a certain fixed central point. To wind a set of spools of irregular or defective form-that is, a set in which each spool has the same degree of irregularity-it is required to have the traverse rod make an increasing variable traverse, or to travel different distances relative to a fixed central point.

The objects of my invention are to provide a spoofing-machine which may be readily adjusted to wind perfectly spools of standard forms, and again, by an easy regulation, may be adjusted in a ready manner to wind perfectly a set of irregular spools having the sam and any-degree of irregularity.

To the above ends my invention principally consists in the novel constructions and arrangements of the sliding shaper-carriage and the independently adj nstable shapers, which shape and control the winding, whereby the traverse-rod carrying the thread-guides may have an increasing traverse either uniform or variable; further, of the peculiarly co-operating shaper carriage and traverse slide,

whereby the latter serves to advance the former, which automatically limits the traverse of the latter; further, in the reversinglever and the coacting means for engaging and disengaging the saddles and traversechanger; also, in a stcp-by-step mechanism which is actuated indirectly by the traverserod for advancing the shaper-earriage; also, in the adjustable means for automatically stopping the traverseehangcr when thespools are filled, which means are operated by the traverse-rod; further, of the novel constructions and arrangements of the several coacting devices and the conjoined parts, as here iuafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 represents a front elevation'of my improved machine. Fig. 2 represents a top plan view of Fig. 1. Fig. 3 represents a rear elevation of a portion of the machine, the spool-spindle and traverse-rod being partly omitted. Fig. 4 representsa sectional view of the machine, taken on line 4 4, Fig. 2. Fig. 5 represents a sectional view of a part of the machine, taken on line 5 5, Fig. 4. Fig. 6 represents asectional view of a part of the machine, taken on lined 6, Fig. 4. Fi 7 represents a sectional view of the end bearing for the spool-spindle, taken on line 7 7, Fig. 2. Fig. 8 represents an enlarged sectional view taken on line 4 4, Fig. 2, and with the actuatingweight for the shapcr-carriage removed. Fig. 9 represents an enlarged detail top view of the device for gradually advancing the shaper-carriage and controlling the shipper-shaft. The guides for the carriage are shown broken off, and the puslrplate in full. Fig. 10 represents an enlarged side view of a thread-guide mounted on the traverserod, shown in section. Fig. 1L represents atop view of the shipper-shaft and adjuncts, the trippingarm, and of the pinion-shaft and tripstud in section; also portions of the machine-frame A and traverse-slide H. The broken-line position represents the trippingarIn placing the tilting-arm of the shipper shaft in position to be actuated by the traverseslide traveling in direction of the arrow, so as to subsequently ship the power-belt.

In the said drawings like letters of reference designate corresponding parts throughout.

Referring to the drawings, A designates the machine frame,which, as shown, is composed of two broad upright and parallel pieces connectcd by a horizontal piece, A. The posts B B support hearings in which the spool-spindle E is journaled and turns, and the post 0 is provided with a bearing in which the traverse-rod F is loosely mounted. The frame and posts are preferably secured firmly to a bedplate, D, which may be of any preferred form or size. The shaft G is journaled horizontally in the machine-frame, and carries at one end a coupling, 6, for the spool-spindle E, and at the other end is provided with a fast pulley, g, by means of which it is rotated. The traverserod F extends horizontally through the broad sides of the 1nachine-frame,and is so set therein astohaveafreclongitudinal movement. Upon the traverse-rod is mounted the traverseslide, composed of three separate arms, H, (see Fig. 5,) which are arched near the free ends, as shown in Fig. 8, where they are secured together by means ofa fiat plate, I. The central arm H is provided with a small roller-hanger, J, tracking on a supporting-rod, J, set rigidly across the machine-frame parallel to the traverse-rod. The traversechanger K is a shaft loosely mounted through and between the sides of the frame parallel to the traverse rod. The traverse-changer is oylindrical,and has the two halves of its length reversely screw-threaded, and is situated within the arches of the arms H of the traverse-slide, and at one end is provided with a loose pulley, 7s, and a fast pulley, k, by which it is operated.

Beneath the right and left hand screwthreaded portion of the traverse-changer K is set atoothed roll, L, upon which are arranged two sets of teeth, each set extending longitudinally of the roll and over onehalfof its length, and the two sets being disposed out of aligir ment, as shown. The ends of the axle of the roll are journaled in the free ends of a U shaped frame, M, placed nearly horizontally and pivoted upon a fixed shaft, N, running parallel to the roll, and the ends of which are set in the sides of the machine-frame. The ends of frame M rest upon springs m, supported by the machine-frame, for the purpose of at fording a necessary yielding action to the roll L. The pawlplates 0 (see Fig. 6) are also pivoted upon shaft N, and their free ends rest upon the upper side of roll L, so as to engage each with one'sct of teeth on said roll. Owing to the alternate arrangement of the two sets of teeth on the roll, it will be seen that while the free end of one pawl-plate is engaged between the teeth of one set the free end of the the free ends of the arms P are-provided with rollers 19, resting each upon one of the pawls O. The upper sides of the ends of the arms P each carry a saddle, 1J2, screw-threaded on the upper concave face, either right or left handed, in order to engage and mesh with the respect ive halves of the traversechanger K. From this construction it will be obvious that when one of the'pawl-plates O is raised upon the high point of a tooth of one set on roll L the other pawl 0 will be depressed between two teeth on the other set of said roll, and by virtue of this action the shiftingarms P will be alternately engaged and disengaged with the traverse-changer K by means of the saddles p being elevated and depressed by the device described. The saddles p are right and left hand screw-threaded to cause each to conform with its coacting half of traversechangcr K, and hence if the former saddle be engaged with traverse-changer K the rotation of the changer will cause the shifting-arm P to travel to the right and carry the traverse-rod F in that direction, and if the latter saddle be engaged with said changer its rotation will serve to move the other shiftingarm P to the left, and likewise the traverse rod F. In these reverse motionsthe traverse-changer runsin the same direction at all times. Each saddle comes into engagement with the traverse-changer at the center of the latter and works along the changer toward the sides ofthe machine-frame, and when one shifting-arm has completed its traverse the attached saddle is automatically thrown out of engagement, and the saddle of the other arm is thro wn into engagement, with the changer in order to reverse the traverse of the travcrse-rod F. The means whereby this is accomplished will now be described.

The reversing-leverQ (see Fig. 3 is athrecbranched Y-shaped body pivoted near the branch on a pivot, q, fixed on plate I. Near the end of each of the branches of lever Q is arranged a spring-actuated click or pawl, q, (see Fig. 8,) suitably set in a cylindrical body, as shown. The clicks 1 are kept in constant engagement with the roll L, and the reversinglcver Q may be rocked on its pivoted bearing q, so that the engaged roll L will receive a stepby-step motion in the direction of the movement of the hands of a clock as viewed from Fig. 8. In order to rock or reverse lever Q on its bearings, able shaper-stops, a, to trip the upper end thereof. TheuprightstandardsA aresecured upon base-plate D, and a is a cylindrical bar set rigidly across from said standards parallel to thetraversechanger'K. The shaper-stops aare set, by means of an eye therein, on bar a, and can be slid in either direction on said bar. The trip-collar R is also loosely mounted on bar a and slides thereon between the two shaper-stops a, which thereby limit the travel of said collar.

The stem of the Y-shaped reversing-lever Q has the end forked, as shown clearly in Fig. 8. In these forks are longitudinal slots, opposite I employ a pair of adjust IIO and parallel, in which work loosely the fixed screws r, set at opposite points on trip-collar R, which lies in the fork of the stem of lever Q. Owing to this construction, the reversing-lever Q is reversed by virtue of the shaper-stops a being fixedly set at predetermined points and allowing the tripcollar a definite traverse, and as the leverQ is carried by plate I while the latter is moved by the traverse-rod F through the medium of the shiftingarms P, their saddles, and the traverse-changer K, the t.rip-collar will be accordingly slid on rod or, and will be tripped by either one or the other of the shaper-stops a, thereby tilting lever Q and.

actuating roll L to operate the pawls O, which serve to engage one saddle and disengage the other, so as to reverse the traverse of the traverserod F in an obvious manner.

Since the shaper-stops a shape and control the winding of the spools by graduating the length of the successive layers of thread, it is necessary that the said stops should be adj nstable toward and away from each other, and that they then be governed to make a gradually-increasing adjustment or divergence, in order to regulate the traverse of the traverserod carrying the thread-guides.

In winding spools of standard forms the shaperstops are predeterminately set at points equidistant from a certain fixed central point, according to the size of the set of spools to be wound, and the stops are governed to make increasing uniform, adjustment or divergence to accord with the form of the spools; but it will be readily seen that any means which is only capable of a uniform degree of gradual adjustment of the shaper-stops would not be capable of producing a perfect winding upon a set of irregular or defective spools having the same irregularity each. Thus to aceomplish the winding of spools of irregular forms the shaperstops must be controlled to have an increasing variable adjustment or divergence--that is, the movements of the stops away f1 orn a fixed central point must be of different distances in order to build the thread against the spool-flanges having different angularities.

In order to render spoofing-machines capable of perfectly winding not only regular but also irregular forms of spools, I have devised the following adjustment, and will proceed to describe the same as embodied in the preferred construction shown.

Upon the opposite ends of the side pieces of frame A from the standards A are placed two posts, A", connected by a fixed bar, a and the upper ends of standards A are connected by means of the two fixed bars a lying in the same plane and apart, just above bar a, parallel therewith. The two guides S are set at right angles across the bars a and bar a, upon which they are fixed by fast collars a, set on said bars, so that said guides lie midway between the broad sides of frame A. The shaper-carriage T (see Fig. 2) slides to and fro on guides S, and is a T-shaped body provided with a flange, 25, extending downwardly at right angles thereto, and which works between said guides. The slot i is formed in the flange t to allow it to work over the bars a. The curved slots 1 are formed symmetrically, one in each side of the cross-head of the Tshaped carriage T, and in said slots work the binders a, which may be moved therein and clamped securely at any points. The binders to consist each of a screw-threaded shank having a head and of a thumb-nut working in the shank, as will be understood by referring to the drawings. Near the end of the stem of carriage T is fixed a cross-piece, t, at corresponding points on which are swiveled the corresponding ends of the shapers U. The other ends of said shapers are each provided with a binder, a, working in the guideway a of the carriage. The shapers U are flat straight bodies, and from their arrangement and construction it will be evident that they can be readily adjusted relative to the central line of length of carriage T and relative to each other-that is, they may be both sctat the same angles with said line, or may each be set at a dili'erentangle therewith. Of course the shapers are adjusted and rigidly set by means of binders a being adjusted and clamped. In each guideway it works a guide-pin, 22, formed one on each of the stopcarriers V, which are flat three-cornered pieces traveling freely on bars a as shown. The stop-carriers V are adjnstably connected one with each of the shaper-stops a by means of the screw-stems a fixed to said stops, and the adjusting-nut a, working on the stems, whereby the stops may be spaced as required by the varying sizes of spools to be wound. By \"irtue of this con strnction, if the shapers be set and fixed at equal angles relative to the carriage, as shown in Fig. 2, and the sharper-carriage be slid toward the back of the machine, the controlled shaper-stops, predeterminately set, will be slid apart, as described, by the guide-pins in a uniform manner, and each will travel equal distances. On the other hand, if the angles of the adjustment of the shapers be different relative to the carriage, the sliding of said earriage will cause the shaper-stops to diverge or move away from each otherin avariable man ner, and each will travel different distances proportionate to the difference of adjustment.

of their controlling shapers, respectively.

The figures show the machine as set at one limit of traverseof the traverse-rod F and the coacting parts, and necessarily said rod will make its least traverse for winding that layer before the shaper carriage begins to slide, and will make gradually-increased traverses as the carriage slides back ward,and its greatest traverse will occur when the carriage ceases to move and the last layer of thread is to be laid.

In order to effect the gradual movement of the shapercarriage necessary to the required variation in the position of the shaperstops a, I employ the following arrangement: Upon its one side of a projection of flange t is screwset a rack-bar, i (see Figs. 5 and 8,)disposecl parallel to the length of carriage T. The pinion-wheel w is in mesh with rack-bar i (see Figs. 5 and 8,) and is keyed upon a vertical rotary shaft, \V, the lower end of which is journaled in a stand, A, set on cross-piece A of the machine-frame, and the upper end is journaled in a bracket, 8, (see Fig. 2,) fixed upon one of guides S; Below pinion 10 (see Fig. 9) the ratcl'iet-whecl Qs'is keyed upon shaft XV, and between said pinion and ratchet is loosely mounted the movable arm X on said shaft. The outer end of arm X is provided with an anti-friction roller, and carries also a pawl, 00, which is kept in constant engagement with ratchet w by means of spring a, set be tween the pawl and arm X. The arm X is n'iaintained in contact with puslrplate it (see Fig. 9) by means of spring at, lying between said arm and the adjacent guide S, so that its anti-friction roller bears against the edge of said push-plate. The push-plate travels in company with the traverse-rod by means of being adjustably mounted on bracket 71, carried upon the traverse-slide, which is actuated by said traverse-rod.v Thus, as the traverserod travels toward the left-hand side of the machine in the figures, the traverse-slide earries the beveled edge of push-plate h against the antil'rietion roller on the movable arm X, and so forces the same outwardly and causes the pawl 00 to rotate the engaged ratchet w, and thereby advance the shapercarriage through the medium of the shaft XV and'pinion w in mesh with rack bar 'L". This gradual advance of the shapercarriage is sufficient to move the shaper stops away from each other the required distances to increase the length of the traverse of the traverse-rod for the succeeding layer ofthread. \Vhen the push plateh has traveled away from the arm X, the same will recedc and allow its pawl to engage with the next tooth to be sub scquently ad vanced,as described. The shapers being once adjusted, the machine will automatically operate the shapcr-stops to control the traverse of the traverserod to accord with said adjustment of the stops.

The operation of the sliding or advancing device for the shaper-carriagc is madeagainst the action of a weight, y, attached to one end of a cord or chain,j, leading over a pulley, s, set between guides S, the other end of said chain being attached to a forward extension of flange t of the shaper-earriagc. Thus the tendency of the weight y is to draw the carriage toward the front of the machine, while that of the pawl-and ratchett'levice is to draw said carriage toward the rear of the machine. \Vhen the pawland-ratchet device has drawn the carriage to the full limit of travel, the pawl is to be disengaged from its ratchet by pressing on handle a" of the pawl,whereupon the weight 3 will automatically return the carriage to the front of the machine.

In order that the machine may automatieally ceaserunning when the spools are wound full, the ratchet-wheel 10' (shown enlarged in Figs. 8 and 9) is formed witha set of sockets in the body of said wheel for the insertion of the movable trip-stud w Since every action of the push-plate it upon the ratchet 10 ad vances the same one tooth in rotation,the tripstud may be placed in a predetermined socket, so that when the machine is to be stopped the stud will trip a tripping-arm, Z, (shown enlarged in Fig. 11,) and will effect the shifting of the driving-belt (not shown) from the fast to the loose pulleyJc and 7;, respectively. The tripping-arm is pivoted on shaft \Vjust below ratchet w. The trip-stud 20 is moved in the direction of the arrow, Fig. 11, and trips the arm Z into the broken-line position. (Shown in said figure.) This tripping arm Z engages the tiltingarm Z, mounted on the shippershaft Z provided with a shipper, z, and journaled in machine frame A. \Vhen the tilt.- ing'arm Z is thrown over in the direction of the arrow by the arm Z, it lies in the path of the moving traverse-slide and is struck by an arm, H, thereof, moving as per the arrow adjacent, and is then borne along with the slide until the belt isshippcd, by virtue of the shipper-shaft being carried lengthwise on its bearings in the direction of the arrow parallel therewith. \Vhen the machine is to be started running again, the shipper is forced in by hand, the tilting-arm Z being retracted by spring 2.

The thread-guides, one of which is shown enlarged in Fig. 10, consist each of anarni,O, having an eye therein, by means of which it is set loosely on traverse-rod F. To the pin C on arm 0 is fixed the end of a coil'spring, c, the other end of said spring being fastened upon the binding-collar 0, which is adjustable on rod F by means of the set-screws c, and is set fast in position, this permitting of the arm C being tilted on its bearings with a springpressure, the collar 0' remaining fast. The number of threadguides may be increased or diminished to accord with the number of the spools 8 to be wound during each run of the machine.

The post B carries a bearing, 1), for the spoolspindle E, and this hearing has a hinged cover, b, by raising which the spindle may be removed. Thepost B carries a peculiar separable bearing, 1)". (Shown clearly in section in Fig. 7.) This bearing consists of an eye to receive an internally screw-threaded tube, I), within which works a screw-bar, I), provided with ajain nut, b The inner end of tube 1) is enlarged to receive a socket, b, which is held by screws b projecting into an annular groove formed around the socket I), and arranged to receive the end of spindle E, said spindle having a groove to receive a spline on the interior of socket'b. The perforation 1) leads from the outside of the tube 1) to the space formed about the inner end of socket Z) and allows the oil to be fed to the socket-bean ing. By this means the oil is fed between the end of the tube b and socket b and does not reach the end of spindle E. The tube b is held in eye b by ascrew, 12 The bearings of posts B, B, and O are provided with stems eX- tending down in said posts and held adjustably therein by bindingscrews b", the purpose of mounting the bearings adj ustably upon said posts being to facilitate the leveling of the spoolspindle and traverse-rod.

The general operation of the machine is as follows: The spool-spindle is first supplied with the desired number of empty spools, there being a corresponding number of threadgnides mounted on the traverserod. The shapercarriage is placed at the forward limit of travel upon the guides. The shapers are then adjusted at the same or different angles to the center line of length of the shaper-carriage, according as the spools are of a regular or irregular form, and in this position they are firmly set by means of the binders. The machine is started and the traverse-rod travels in one direction by means of one shiftingarm, and is then reversed and travels in the opposite direction by means of the other shiftingarm. The motion of the traverse-rod serves to slide the shaper -carriage on its guides, through the mediums of the push device and the step-by step mechanism, and thereby increase the space between the shaper-stops for the trip-collar, controlling the reversing-lever, to travel in, and so the device for engaging and disengaging the shiftingarms is governed and the traverse-rod regulated. Thus the machine works on itself automatically until the required number of layers have been wound, when the predeterminately-set trip-stud affects the belt-shipping device to stop the machine. The spool-spindle is now detached and the wound spools removed therefrom, after which the shaper-carriage is set back to its startingplace and the spindle with a fresh set of spools is replaced in the machine and the above described operation repeated.

There may be various modifications made in the principal parts of the machine here shown and described without substantially departing from the spirit of my invention as herein described and claimed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
